Introduction WWarning Read "Safety Information" before using the Calibrator. The Fluke 725Ex Multifunction Process Calibrator (hereafter referred to as “the Calibrator”) is a handheld, battery-operated instrument that measures and sources electrical and physical parameters. For a summary of source and measurement functions, see Table 1. In addition to the functions in Table 1, the Calibrator has the following features and functions: • A split-screen display - The upper display allows the user to measure volts, current, and pressure only. The lower display allows the user to measure and source volts, current, pre ...

on the other equipment must exceed the Voc and Isc ratings for the terminals connected to on the 725Ex calibrator. In addition to matching voltage and current entity parameters, it is also necessary to verify that capacitance and inductance has not been exceeded. Again, the Calibrator CCD identifies the maximum capacitance (Ca) and maximum inductance (La) that is permitted based either on the intrinsic safety barrier ratings or on the Calibrator ratings for the specific terminals used. As an example, the Calibrator CCD explains that the capacitance of each unit connected in th ...

Ex Hazardous Areas 5 W Warning To prevent fire, explosion, or personal injury: • Use the Calibrator only as described in this User Manual and the Fluke 725Ex CCD (Concept Control Drawing) or the protection provided by the Calibrator may be impaired. • Inspect the Calibrator before use. Do not use it if it appears damaged. • Check the test leads for continuity, damaged insulation, or exposed metal. Replace damaged test leads. • When using probes, keep fingers behind the finger guards on the probes. • Never apply more than 30.0 V between the input terminals, or between any terminal and earth ground. • Applying ...

function. • When measuring the pressure of toxic or flammable gases, care must be taken to minimize the possibility of leakage. Confirm that all pressure connections are properly sealed. • Do not use in a damp or wet environment. WCaution To avoid possible damage to Calibrator or to equipment under test: • Disconnect the power and discharge all high-voltage capacitors before testing resistance or continuity. • Use the proper jacks, function, and range for the measurement or sourcing application. • The MEASURE/SOURCE terminal ...

Ex Hazardous Areas 9 Faults and Damage Applying a voltage greater than 30 V to the input of the Calibrator invalidates its Ex Approval and may impair its safe operation in an Ex-hazardous area. See “Ex Hazardous Areas”. If there is any reason to suspect that the safe operation of the Calibrator has been affected, it must be immediately withdrawn from use, and precautionary measures must be taken to prevent any further use of the Calibrator in an Ex-hazardous area. See Ex Hazardous Areas. Fully observe all instructions, warnings, and cautions contained in this manual. In case of doubt due to translation and/or printi ...
